Abstract

All-in-one safety syringe comprises: a hollow barrel, a plunger with a piston, a removable luer lock, a needle in additional with an adaptor enabling to fit with the medical equipments. The piston includes a rubber element having a central room space to allow the plunger tip to move axially therein for performing functions to enable drawing. fluid starting at 0cc level and interlocking respectively. The luer lock affixed at a distal protruding nose of the barrel can lock with the needle wherein a female interlocking structure at proximal end to receive a male interlocking structure aligning an intruding means of the plunger, characterized in that the male interlocking structure is staying within, carrying the luer lock with the needle into the barrel upon retracting the plunger in the trapping manner within the barrel. Further pulling the plunger, the piston is abutted allowing the plunger to break at a fragile portion provided, thereby absolutely ensuring non-reusable and avoid needle stick injuries. Additionally, the adaptor can be interlocked with the luer lock tightly for opposing the big pressure caused by the operation of medical equipment via catheter when carrying out multiple medical applications.
